Clamp on Portable Ultrasonic Flow Meter

The Transit time Flow meter of measures flow rate by calculating the spreading of an ultrasonic wave in a liquid, going upstream and downstream go into a full pipe.  This flow meter is mostly used to measure the flow rate of homogeneous fluids, with a very little percentage of suspended solids and possibly without gas bubbles.  Its peculiar installation makes these devices suitable for measuring aggressive fluids 9acids, basic and dissolvent’s)  or very soling fluids (oil and fuels).  The measuring system is  composed of one or more couples of ultrasonic transducers acoustically coupled to the external pipe’s wall (it is also possible to use transducers in direct contact with fluid to be measured) and a portable unit elaborating the sent and received signals from the transducers.   The HOST unit has a DSP microprocessor; it gives signals to interfacing with the process or the control systems
